In the basic protection and medical work environment, we will encounter the dangers of bacteria, harmful ultra-fine dust, acid solution, salt solution and corrosive chemicals. For these dangers, we need to use protective clothing to protect the whole body of workers. Protective clothing is also known as work clothes. What are the characteristics of protective clothing? What are the non-woven fabrics used in protective clothing?
Breathable protective clothing for basic protection
It is suitable for automobile, aviation, food processing, metal processing, mining, oil and natural gas operation. Generally from the head to the shoulder to the body, the cap is connected, and the cuffs and trouser cuffs are tightened.
Protective clothing is required to effectively block the entry of dust and solid particles in the working environment. Wear comfortable and breathable, and not easy to fall dust. It has strong protection and can block slight splashing in low-risk areas.
This kind of protective clothing is made of SMS non-woven fabric. In the structure of SMS material, the structure characteristics of ultra-fine melt blown fiber layer and high strength spunbonded non-woven layer make the material have certain hydrostatic pressure resistance and air permeability, which form the basic isolation performance of SMS material.
In addition, SMS non-woven fabric also has barrier property, which is used in a variety of protective clothing products, including high and low end medical protective clothing, industrial protective clothing, chemical protective clothing, etc.
Of course, in addition to SMS non-woven fabrics, there are PE film composite non-woven fabrics, breathable film non-woven fabrics, spunbonded non-woven fabrics can be used as medical protective clothing fabrics.
Medical protective clothing
Medical protective clothing, also known as medical protective clothing, is the work clothes of medical staff, that is, protective clothing for the body of medical workers. It is mainly used to isolate bacteria, harmful ultra-fine dust, acid solution, salt solution, corrosive chemicals and keep the environment clean.
Characteristics and uses of medical protective clothing
(1) Ordinary PP non-woven protective clothing
It is made of PP spunbonded nonwovens, with a weight of 35-60gsm. Features: breathable, dust-proof, not waterproof, good tensile resistance, the difference between the front and back is not obvious. PP spunbonded non-woven fabric is used for general isolation clothing, low-grade isolation clothing and patient clothing.
(2) Non woven protective clothing covered with film
Fabric is coated non-woven fabric, the general use of gram weight 35-45gsm. Features: airtight, waterproof, bacteria isolation effect is good, there are obvious positive and negative distinction, body contact side is non-woven, not allergic, feel good. There is a layer of plastic film outside to prevent liquid leakage, which is used in the occasions with pollution and virus. The main use of hospital infection ward is covered non-woven protective clothing.
(3) SMS non woven protective clothing
The three-layer composite non-woven fabric has a waterproof and bacteria isolating layer in the middle and a sesame dot SMS non-woven fabric in the outer layer, which is strong and tensile, and has the function of isolation, waterproof and air permeability. Generally, it weighs 35-60gsm. SMS non-woven fabric is used for surgical clothing, surgical hole towel, isolation clothing, test clothing, operating clothing, non-surgical masks, and visitors' clothing.
(4) Non woven protective clothing with breathable film
PP polypropylene is used, covered with PE breathable film. Generally, 30g PP + 30g PE breathable film is used. Therefore, it has strong air permeability, better impermeability, high impact resistance and resistance to various organic solvents and acid-base corrosion.
Strong mechanical properties, soft and comfortable texture. It is non combustion supporting, non-toxic, non irritant and harmless to skin. It is the most advanced medical protective clothing for medical protection, which is bacteria proof, waterproof, slightly breathable and soft in texture.
Its characteristic is that the sweat gas of human body can be sent out, but the harmful gas and water outside can't be invaded. In addition, the non-woven fabric with permeable membrane is also used in surgical clothing, surgical hole towel and isolation clothing.
